Embodiment

Fig. 1 a illustrates the synoptic diagram of the optical display 10a of not drawn on scale.Optical display 10a comprises: casing 12; Back light unit 14, it has reflector plate 16, photoconduction 18 and light source 20; Diffusion sheet 22; Prism film 24 and 26; Diffusion sheet 28; Reflecting polarizer 30; Bonding coat 32; Display panel 34; Optical film unit 36 (forming) by element 22~32; And optical film package 38 (forming) by optical film unit 36 and photoconduction 18.

Casing 12 normally is used for the plastic frame of the parts of support of optical display 10.In the present embodiment, back light unit 14 comprises one deck or more multi-layered reflector plate 16 and photoconduction 18 and light source 20.Photoconduction 18 can comprise the specific features part that is used for direct light, and dull and stereotyped form shown in can taking or other form such as wedge shape for example.

Light source 20 can be the light source of any adequate types such as fluorescent light, light emitting diode or direct illumination formula for example.From the light of light source 20 via photoconduction 18 directed toward display panel 34.

Next, diffusion sheet 22 is stacked on the photoconduction 18.Diffusion sheet 22 homogenising are from the light intensity of photoconduction 18.

Prism film 24 and 26 is stacked on the diffusion sheet 22.Prism film 24 and 26 comprises and is used for the prism array of photoconduction to display panel 34.Prism film 24 and 26 can arrange so relative to each other that is: their prism arrays run parallel perhaps more is typically, and their prism array is not parallel.As shown in this embodiment, prism array is perpendicular to one another.

Diffusion sheet 28 is stacked on the prism film 26.The diffusion sheet that diffusion sheet 28 is normally more weak, and, be used for the homogenising light intensity so that it is more even as described in about diffusion sheet 22.

The last stacked film that illustrates is a reflecting polarizer 30.Reflecting polarizer 30 can be any reflecting polarizer that comprises in the multiple reflecting polarizers such as multi-layer polymer film, cholesteric polarizer or wire grid polarizer.Reflecting polarizer 30 reclaims and is in wrong polarization state and can not be as the light transmissive light of image.

Usually, reflecting polarizer 30 is laminated to the rear portion of display panel 34.Yet in the situation shown in here and the following example, reflecting polarizer 30 also can pile up with other blooming.

Following one deck is bonding coat 32 (representing with thick line).Bonding coat 32 is the rim strip or the shadow frame of double-coating normally, but also can be adhesive coatings.A surface of bonding coat 32 is a black, and contact display panel 34.Opposed surface is colored as white or silver color, and contacts the part of its each layer of below.Light leaks around rete easily, and the light that the reflecting surface recovery of bonding coat 32 is revealed is so that its changed course.Black surface has reduced " halo effect " around the optical display, i.e. the bright line that forms along the display periphery sometimes.Operable suitable rim comprises Black and White Double Coated Polyester Tape4003S, the 4003T, 4007,4037 and 4040 and Black and White Double CoatedPolyester Tape 5173 of 3M company.If desired, also can use the Black andWhite Single Coated Polyester Tape 4038 and 4039 of 3M company.

Should be noted that layer 22 to 30 is represented an embodiment.As required and hope, can omit, add or replace some layers in the layer 22 to 30.For example, the turning film that its prism faces upward or downward can replace prism film 24 and 26, perhaps can add Vikuiti BEF-RP 90/24 reflecting polarizer that has prism.In addition, each layer diminishes gradually, and its edge or periphery are recessed successively, so that make the part of each layer contact bonding coat 32, this is explained in more detail further below.
